Isariopsis lawa (Ell.) Sace. 
On leaves and pods of beans (Phaseolus vulgaris), Clark County, 
Indiana, August, 1920. 3816. 
So far as the writer is able to learn, this is the first time this 
fungus has been recorded as injuring or growing upon bean bods. 
During the month of August, 1920, and to some extent during the 
same month of 1921, a number of gardens were completely ruined 
by this disease. It appeared first upon the leaves, then attacking 
the pods, spotting and rotting them. The appearance of the spots 
upon the pods is entirely unlike that caused by anthracnose. 
They are usually larger, more superficial at the beginning, and 
present a blotched appearance around the edge. Further work is 
being done to determine more definitely the exact nature of and 
the conditions necessary to cause bean pods to be severely injured 
by this fungus. This fungus was first noted in America by Ellis 
under the name of Graphium laxum Ell. Bull. Torr. Club, 1881, 
p. 65. 
Ramularia Plantaginis Pk. 
Stei 
On living leaves of Plantago Rugelii, six miles west of Blooming- 
ton, July 25, 1920. 3833 and 3858. 
Our specimens have spots 1 mm. to 2 cm. in diameter, brown, with 
small light colored center. Specimen number 3633 has much smaller 
spots than 3858. Conidiophores amphigenous, and especially abun- 
dant near the outer edges of the spots, wavy in outline, and bear- 
ing spores laterally as well as terminally, about 25 microns long. 
Spores cylindrical, rounded at the upper end, somewhat truncate 
below, 12 to 45 by 4 to 5 microns, continuous, becoming 1 or even 
2 or 3-septate. This fungus corresponds well with the too brief 
description by Peck in Report 32, 1879. Ramularia Plantaginis 
Ell. & Mart. is said to have minute spots. The descriptions of 
these two species, however, seem, in the light of our material, to 
be near if not identical. From the fact that conidiophores are 
found in the outer brown part of the spots, it seems better to 
describe spots as brown with pale center rather than, spots small, 
pale with broad border. Since Peck’s description antedates that 
of Ell. & Mart., it seems preferable to refer our specimens to R. 
Plantaginis Pk.

the descriptions.
